Sorry, it looks like I misunderstood what you meant by "saftey, security, and sanitation". Those things are usually part of the responsibilty of who-ever's in charge i.e the manager. In the UK, if these things aren't in place, the place can and probably will get shut down. As such, it is law to have employees who may or may not be the manager to have sufficient training in these areas, especially if the person is one who prepares food.
Just so you know, my family has 7 restaurants/take-aways/cafes and I have personally have run one of them for about half a year while "the old folks" took half a year off so it isn't like I don't know this business works.
